Finally managed to figure it out.
The difference, as documented in this ticket, is that Postgres 9.1 has standard_conforming_strings on by default. Which wouldn’t be a problem, really, except Django’s adapter has a bug that basically ignores it. A patch was submitted and it’s working for me.
For those unwilling or unable to apply the patch or upgrade, you can just use this database adapter instead.
